Filed: 1992-09-29
Abstract: PURPOSE:To obtain a production method of color filters with a highly precise pattern excellent in spectroscopic characteristics for electrophotography, by forming a high-insulating black matrix pattern as the first color between picture elements. CONSTITUTION:After a photoelectrifying layer 4 is charged into negative by corona discharge, the layer is exposed through a chromium mask 8 to remove charges in the pattern, and dispped in a black toner liquid and developed to form a black matrix pattern 10 for the first color on the transparent conductive layer 2. Then the photoconductive body is electrificed into negative and exposed through a picture element mask 11 to remove charges in the area for the second color pattern. Then the photoconductive body is dippsed in a red toner liquid and developed to form red picture elements 14. By the same procedure, green picture elements 15 and blue picture elements 16 are formed. By this method, electrostatic latent image potential can be maintained uniform by electrification and exposure even when coloring of picture element proceeds. Thereby, high precision pattern excellent in color spectroscopic characteristics can be obtd.
